BGT007H cells for advanced digestive cancer
This trial tests a new cell therapy called BGT007H for people with advanced digestive tract cancers (esophagus, stomach, pancreas, or colon) that have not responded to or stopped working after at least two prior treatments. The goal is to see if this therapy can help shrink tumors or slow the disease.
Xuzhou, JiangsuAges 18–70 - NCT01696734RecruitingPhase 3

A study on megestrol acetate for weight loss in advanced digestive cancer
This study tests a special form of megestrol acetate (a medicine that can help with appetite and weight gain) in people with advanced digestive system cancers who are about to start or are already taking a type of targeted therapy called a TKI. The goal is to see if it helps with cancer-related weight loss and wasting (cachexia).
Shenyang, LiaoningAges 18 years+ - NCT06855524RecruitingPhase 2
Seaweed supplement to prevent fatigue during chemo
This trial tests whether a natural supplement called fucoidan (from seaweed) can help prevent the fatigue often caused by chemotherapy. It is for people with gastrointestinal or gynecologic cancer starting a platinum-based treatment plan.
Scottsdale, ArizonaAges 18 years+ - NCT06798545Recruiting
Study of a new navigation system for pancreas EUS
This trial is testing a new navigation system to help doctors see the pancreas during an endoscopic ultrasound (EUS) exam. The system may make it easier to spot lesions or other problems in the pancreas.
StrasbourgAges 18 years+ - NCT03884075RecruitingPhase 2
Semaglutide study for fatty liver and how sugar affects the liver
This Phase 2 study tests how semaglutide (a diabetes medication also used for weight) affects fatty liver and the liver’s response to sugar. It may help people with non-alcoholic fatty liver disease understand whether the drug improves liver fat and related changes.
Bethesda, MarylandAges 18–100 - NCT07061080RecruitingPhase 2
Tarlatamab for advanced digestive neuroendocrine cancer
This trial tests a new drug called Tarlatamab for people with advanced neuroendocrine carcinoma (a rare and aggressive cancer) of the digestive system that has stopped responding to prior chemotherapy. The drug targets a protein called DLL3 found on some tumors, and researchers hope it can shrink or slow tumor growth.
Brest, BrestAges 18 years+ - NCT06349044Recruiting
Radiation and immunotherapy with or without probiotics for advanced digestive cancers
This trial tests if adding a probiotic (Lactobacillus rhamnosus M9) to standard radiation and immunotherapy can help people with advanced digestive system cancers. It aims to see if the combination is more effective and safer than the standard approach alone.
Hangzhou, ZhejiangAges 18–75 - NCT04221893Recruiting
Radiation therapy for metastatic gastrointestinal cancers
This trial tests whether adding radiation therapy to your current immunotherapy can help control cancer that has spread in the digestive system. It aims to improve symptoms and possibly slow the cancer's growth.
San Francisco, CaliforniaAges 18 years+ - NCT05356520Recruiting
Which operation is best for Siewert type II stomach cancer
This trial compares different surgical approaches for removing Siewert type II cancer at the esophagus–stomach junction. It aims to find which operation works best for people who can have the tumor removed.
Xi'an, ShaanxiAges 18–75 - NCT07550673RecruitingPhase 4
Upadacitinib vs. Infliximab for Severe Ulcerative Colitis
This study compares two medications—upadacitinib and infliximab—as second-line treatments for acute severe ulcerative colitis (a serious flare of inflammatory bowel disease). The trial will help doctors understand which treatment works better when standard first-line therapy hasn't controlled the inflammation.
Ankang, ShaanxiAges 18–85 - NCT07263620Recruiting
Gut bacteria and cancer treatment before surgery
This study looks at the bacteria in your gut to see if they can predict how well chemotherapy or radiation works before surgery for certain cancers. If you have pancreatic, stomach, colon, or esophageal cancer that has spread nearby (but not to distant organs), you may be able to join.

Study of experimental drug IDOV-SAFE for advanced digestive cancers
This trial tests an investigational drug for people with advanced digestive system cancers (like colorectal, stomach, or liver cancer) that have stopped responding to standard treatments. The goal is to see if the drug is safe and helps control the cancer.
BeijingAges 18–75 - NCT07283939Recruiting
Testing a tool to adjust chemo doses and reduce treatment delays
This trial tests a computer algorithm called PAGODA that helps doctors adjust chemotherapy doses for people with gastrointestinal cancers. The goal is to prevent unplanned treatment delays while keeping the treatment effective.
Fairbanks, AlaskaAges 18 years+ - NCT03303495RecruitingPhase 3
Second-line chemo with or without bevacizumab for colon cancer
This Phase 3 study compares two treatment plans for people with metastatic colorectal cancer that got worse or caused side effects after first chemotherapy. It looks at whether adding bevacizumab (a medicine that targets blood vessels feeding tumors) improves outcomes versus using a different chemotherapy approach.
Guangzhou, GuangdongAges 18 years+ - NCT03800693RecruitingPhase 2
Shorter vs longer oxaliplatin infusions for gut cancer
This Phase 2 study compares giving oxaliplatin by IV for 2 hours versus 6 hours, along with the standard FOLFOX6 chemotherapy. It aims to see if the shorter infusion works as well and is manageable for people with gastrointestinal cancers.
Atlanta, GeorgiaAges 18 years+ - NCT04666727Recruiting

Study genes and blood markers in bile duct and gallbladder cancers
This study looks at genetic and molecular patterns in people with bile duct or gallbladder cancers, and compares them with people without cancer (or with chronic liver disease). It may help researchers understand why these cancers happen and how to spot risk earlier.
Houston, TexasAges Any age - NCT06023056Recruiting

Common questions
- Are there clinical trials for digestive system disease?
- Yes. Clin2 currently lists 74 recruiting digestive system disease studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a digestive system disease trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a digestive system disease trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
